My old bomb Corolla was pinched in the wee hours of a Thursday morning a few years ago. The Peelers called me when they found it a week later.... the crooks had put their own steering wheel lock on it
I agree with Woomera - if they want it they'll take it. However.....
Imagine someone pinches a lighty next week and prangs it into a school yard. The inevitable "totally unlocked twin engine Cessna Cherokee" headline will be presented as the heart of the matter, not the theft. Most people hate 'those noisy dangerous little planes' as it is. The outrage will be lapped up by the tabloids and their slack jawed readers, listeners and viewers.
We can't ignore perceptions. Islander Jock makes the point well; don't we want to be seen to be complying?
And Sunfish, as most people live in the capital cities, we GA knobs will be spending more than 3 hours on the road just to get to the airport, the way things are heading......
